Spark plug....iridium or not to iridium

[txredxj]

+5 hr crank, bored tb, kbr port, hc3, kenny valve, 11-1 cp piston, pro design k&n, ron woods pipe, pc3. I have looked for maps and asked but they are hard to find for my build. But the map I run is fat but better than the alternative of running lean.

I chose not to go iridium, cost isn't that much more, but still more. I'm stubborn I guess, if someone can show me that it's that much better, I'll switch. People say hotter spark blah blah blah. If you want a hotter spark why not bump up to a hotter plug? I've ran regular plugs.

incorrect.  a hotter plug is not a hotter spark. a hotter or colder plug has do deal with removing temp from the cumbustion chamber not the spark.  normally when you increase the cc temp you should drop to a heat range colder plug.
